app.get('/', function(req, res) {
    var gifStream = htmlToGif(options),
        animatedGif = '';

    // Capture the streaming output
    gifStream.on('data', function(data) {
        animatedGif += data.toString('binary');
    });

    // Once complete, write it out to the browser
    gifStream.on('end', function() {
        res.set('Content-Type', 'image/gif');
        res.end(animatedGif, 'binary');
    });
